Code:
#!/bin/bash

NAME=$(basename $0)
if [ "$1" == "-h" ] ; then
        echo "Usage:  ${NAME} [-h]"
        echo "Option:"
        echo "  -h:  Print this help text"
        exit 0
fi
echo "You gave me these arguments: $*"
exit 0

You might also want to "man 1 getopt" for a more general way of taking comand line arguments. Unfortunately it's a little long and my system doesn't seem to have the examples mentioned in the doc :(
